Defense: Purdue runs, what I believe to be, a 3-4 with a stand-up DE/LB in Danny E. He doesn't put his hand in the dirt but his job is essentially to make plays on the outside and get to the QB. He has done a very good job up to this point of the season with 29 total tackles, 6 TFL's, 4 sacks, 1 INT, 1 FF, and 3 FR's. The front seven is really where the strength of the defense has been all season but the depth is usually the concern. Some young guys have stepped up throughout the season (LB Derrick Barnes for example) but the true strength is in the very experienced LB's. MLB Jawhan Bentley has 74 tackles, 8.5 TFL's, 1 INT, and 3 passes defended, Markus Bailey has 58 total tackles, 7 TFL's, 5 sacks, 1 INT, 1 FR, and 1FF, and TJ McCollum has 40 tackles, 2 TFL's, and 1 PD (McCollum has missed the previous 4 games with injury but is likely to return this week). The two DT's in Robinson and Neal have combined for 3 sacks and 13 TFL's for the season.
The main issue with the defense is the DB's and Purdue has been without their best CB for the last two games...which hurt against Nebraska. Purdue went with a different CB in the second half of the Illinois game and he appears to be a much better coverage CB (Tim Cason). It is an opportunistic defense that 15 TO's on the season but went through a dry spell for two games before getting a TO against Illinois in the second half. Your QB is subject to some INT problems it appears and Purdue has shown a knack for making some defensive plays in the past. If Purdue can get two TO's, they have a chance...especially if they give the improving offense a short field to play with.
Purdue appears to be some what aggressive at times and if Hunte is able to play, you may see Purdue play man to man on the outside to try and bottle up the NU running game. If that happens, it allows the safeties to play the pass better and focus more attention there to help the CB's.
Sindelar has been good at times and shows an ability to play well at times...but the offense has stalled at times with him at the helm. He is a total statue in the pocket BUT he moves better inside the pocket than Blough did. He has an ability to run if a lane opens up but he isn't going to run much of the spread option runs that Purdue was showing with Blough. Likely you will see Jared Sparks, who now plays WR, to get snaps in what Purdue calls their NASCAR package. Sparks is probably one of the best overall athletes on the field and has an ability to throw the ball as he spent the entire spring and summer playing QB under Brohm's tutelage...he'll just have to get coached up a bit on his reads. Likely he'll have RPO's where there are only two passing options (short and medium). Given the chance, he can break off a long run.
Purdue will likely lean very heavily on the running game this week and then try to play action pass over the top using Sindelar's ability to push the ball downfield versus Blough's quick thinking and accuracy on the short routes.
